    Windows Shares - Everyone Group

    Hi All,

    Windows users generally make the extensive use of file sharing. I wanted to know whether there is anyway to remove "Everyone" group being listed which comes by default when creating file sharing on Windows XP/2003 machines. Right now when anyone creates shares, "Everyone" group appears by default even though with Read permissions. But still from security perspective it is not good if someone accidentally shares some sensitive data and forgets to give proper permission on the user workstations. Can this be done through GPO??

    Anyone has any insights into this one?

    Yes, it is possible, but undocumented. I actually have never seen
    the following on the web.

    What you find[1,2] are information about a registry binary called
    SrvsvcDefaultShareInfo. This binary defines the default permission
    when creating a new share (resp. for all old shares with the
    default security descriptor).

    What value to use?

    Do the following:
    1. Create a new share "test" and give it the default permission you want
    2. Go to the following registry key
    and export the binary called "test".
    3. Use this value for

    (best way: export/import the key).
    4. Setup you GPO accordingly.

    As an additional remark: After passing the share-permission, the user still
    has to pass the filesystem permissions.

    two types of permissions
    resource [files etc]
    ntfs [users gpo]

    I seem to remember MS best practice is to give everyone account access to resource, and use group policy to control access
    so that you are only having to consider ONE thread of permissions, not both
    because there are things to remember when altering permissions
    RSoP [Resultant Set of Policy] tool can quickly determine just what your policies have actually allowed

    I posted a thread a little while back, will link later


    but there are other reasons TO remove everyone group
    and it isn't just because you are not on a domain

    starting to ramble now
    better stop

    From a security perspective you shouldn't allow regular users to create shares in the first place.
